I know the difference between POP3 and IMAP(S). First pulls, second usually syncs.
Still IMAP(S) can be used AS POP3. In other words use IMAP(S) protocol for the transfer and then ask remote server to delete (which I suspect is happening by “syncing” to an empty fake mailbox AFTER transfer? Not sure if it is done via some other method.).
Right now, without me doing anything except setting up a few IMAPS connectors, I get mail from my public server, mail gets removed from public server and stays in my NS7 mail server.
I still want that.
I don’t want to edit custom templates or whatever. Can it be done in NS8 too?
If it will not happen, then I (not so) simply have to look for other solutions to implement this.
Mail (and webtop) is is the main functionality of my own NS7 server. If I don’t get the same, there is really no point.
For most other functions I already have containers or VMs in my host (UNRAID).
For now only imapsync is/will be available. The interest for imapsync is that we do not filter the email via an antispam because we talk directly to dovecot.
Available options
Sync remote inbox folder and possibly remove from remote after sync
Sync full remote folders and possibly remove from remote after sync
Do a full remote clone on local
You can create as many sync tasks you need on a local account, no more limited to one like in NS7
